Robotic gastrectomy is proved to be feasible, safe and oncologically correct in many case series. However, a formal randomized controlled trial to compare robotic with laparoscopic or open technique is far to be completed. Nevertheless, robotics can reduce many of technical drowbacks of the full laparoscopic approach, including anastomosis and linphadenectomy of posterior stations. The minimally invasive robotic surgery could lead to abandone both open and pure laparoscopic gastric procedures

I agree with you that comparing well with laparoscopic gastrectomy, robot-assisted gastrectomy is a feasible and safe surgical procedure with clear operation field, precise dissection, better lymphadenectomy, minimal trauma, reduced intraoperative blood loss and fast recovery . However, actually there aren't randomized controlled trials for to evaluate the safety and efficacy of procedure. . The results of two recent meta-analysis suggest that robotic gastrectomy is a better alternative technique to open and laparoscopic gastrectomy for gastric cancer.

I ask you how long after the use of procedures of gastrectomy (B I, BII, Roux, ), the first Randomized comparative studies have come out in the literature ? But how much earlier the publication of the randomized controlled trials, the Roux en Y was considered by surgeons, the technique of choice , if compared with BI and BII?
